There will be changes made to the way AF operate as a result of this unfortunate accident. You can't simply say "oh well it was all legal" and continue with business as usual. IMHO the minimum requirement will have to be changed to the pilots having at least a PIFR if not a Class 1 and all flights conducted as IFR. It is no different to the changes required from EMS rotary operations and parachute ops when there were fatalities.
